I think off the shelf is probably fine for the most part. Mailing lists, IRC, blogging are all available. Live with the limits they impose (embrace constraints!). As for contracts and online signing, my current gig is with a startup here in Vancouver (BC) that's doing just that for small companies that might be useful if some people/groups did want to do NDA's or contracting/employment agreements, etc. (Not linking as I don't want to be too promotional ;)
